I have tried the jpeg_encode with some 5M pixel gray scale pictures. The result jpg file is about 600-800KB, so the compress ratio is about 8:1, but as I know, some photo process software can compress the jpg file to 1/20 only of original BMP file if choose the quality to 70%. so,How can I control this parameter in jpeg_encode to achieve this compress ratio? thanks a lot!
Hi ericbin, do you use tegra_multimedia_api or gstreamer?
yes, what I use is tegra_multimedia_api
Is there any idea?
